DIPPNG DEVICE FOR MATCH-MACHINES.

Specification of Letters Patent.

Patented Nov. 23, 1909.

Application filed .Tune 22, 1909. Serial No. 503,717.

To all whom t may concern:

Be it known that I, OTTO H. LANDVATTER, a citizen of the Confederation of Switzerland, residing at Durlach, in the Empire of Germany, have invented a new and useful Dipping` Device for Match-Machines, of which the following is a specification.

My invention relates to improvements in dipping devices for match-machines of that kind, in which a table covered with the viscous igniting material is periodically raised and lowered, while match-splint carriers guided in two parallel horizontal rails are moved over the table, so that in the highest position of the lattei` the ends of the match-splints can be dipped in the viscous igniting material.

@ne improvement consists in providing a mechanism for moving the table in its high est position through a distance in the same direction and at the same speed as the match-splint carriers, so that during this period the match-splints shall not be displaced with regard to the viscous igniting material and consequently uniformly good heads are formed on the matches.

Another improvement, in case it is preferred, consists in providing special means for feeding forward the match-splint carriers in groups.

I will now proceed to describe my invention with reference to the accompanying drawings, in which- Figure 1 is a vertical section through the dipping device and the series of matchsplint carriers on the line A--B in Fig. 2, Fig. 2 is a vertical section through the line C-D in Fig. 1, Fig. 3 is similar to Figfl and shows the special means for feeding forward the match-splint carriers in groups, and Fig. 4 is a detail, which will be referred to later on. Y

Similar characters of reference refer to similar parts throughout the several views.

Of theframe of the match-machine,which base plates 1, 1 and four standards 2, 2 mounted on them are shown. Two parallel horizontal rails 3, 3 of any construction are fastened on the four standards 2, 2 and are opposed to one another. These rails 3, 3 serve for guiding a series of match-splint carriers 4, 4, which are shown as adapted to guiding two rods 7, 7 which at their upper ends carry two crossheads 8, 8. A horizontal shaft- 9 is mounted to turn in suitable bearings, such as for example 10, 10 in Fig.

2, and is arranged to be driven fromthe 'matchanachine (not shown) in any known manner. On the shaft 9 are fastened two like cam disks 11, 11 and two like eccentric cam disks 12, 12. Two parallel horizontal levers 13, 13 are mounted on two standards 2, 2 to rock at 14, while their slotted free ends engage pins 15 on loose collars 16, 16 or the like fastened on the two vertical rods 7, 7 mentioned above. Two rollers 17, 17 are' mounted to turn on two pins 18, 18 fas tened on the two levers 13, 13 and can roll on the periphery of the two cam disks 11, 11.

' As long as the two rollers 17, 17 bear on the cylindrical parts of the smaller radius of the camfdisk 11, 11, the two rods 7, 7 will occupy their lowest position. However, the moment that theY cylindrical parts of the larger radius of the cam disks 11, 11 and eX tending through the angle of a in Fig. 1 strike the rollers 17l and raise them, the two rods 7,

.7 will be thereby shifted into their uppermost position. A dipping table 19 of any known construction is placed on the two crossheads 8, 8 and can move thereon through a short distance in both directions parallel to the two rails .3, 3.

On suitable arms 20, 20 of the supports 6, 6 two bent levers 21, 22, 21, 22 are mounted to rock, which with their upper slotted ends engage pins 23, 23 in lugs 24, 24 on the table 19. Their lower ends carry two rollers 25, 25, which are adapted to roll on the periphery of the two eccentric cam disks 12, 12. Means are provided for constantly pressing `the two rollers 25, 25 against the cam disks 12, 12. For example. the table 19 may be provided on its left side in Fig. 1 with lugs 29, in which two pins 30 (which in Fig. 2

may be assumed to be behind the pins 23, 23) are fastened. These two pins 30 are connected with two weights 31 by means of vtwo chains 32 passing over two guiding pulleys 33. The two cam disks 11, 11 and the ratio of the lever arms on the two levers 13, 13 are so proportioned, that during the highest position of the dipping table 19 the lower ends of the match-splints 5, 5 can dip in the viscous igniting material 2S on the table 19. The shaft 9 is driven in the direction of the arrow 26 in Fig. 1. The table 19 may be provided along its edges with ledges 27, 27 or the like for holding together the viscous igniting material 28. The eccentric part of the periphery of each eccentric cam disk 12 extends through an angle of b in Fig. 1 and is so shaped, that during the highest position of the table 19 it can be moved forward in the direction of the moving match-splint carriers 4, 4, that is from left to right in Fig. 1, and at the same rate of speed, as the carriers 4, 4 are fed forward. 1n general the two angles c and b may be made alike. The slots 34, 34 in the upper ends of the two levers 21, 22, 21, 22 permit the table 19 to rise.

On account of the ledges 27, 27 along the longitudinal edges of the table 19 it is obviously necessary to leave two gaps 35, 35 between any three neighboring groups or match-splint carriers 4, 4, Fig. 1, for permitting the said two ledges 27, 27 to engage without disturbing the match-splints 5, 5. 1n Fig. 1 each group of carriers 4, 4 is shown as comprising eight carriers 4, 4. The two rails 3, 3 are cut out at 36, 36 for permitting the ledges 27, 27 to engage. The simplest plan of leaving the said gaps 35', 35 is evidently to leave every ninth carrier 4 without anyl match-splints 5, 5, so that the said device for pushing the splints 5, 5 into the holes of the carriers 4, 4 requires in any known manner to be rendered inactive for every ninth carrier 4. Then the whole series of match-splint carriers 4, 4 can be uninterruptedly fed forward by the said device or in any other known manner, while by the mechanism described above the table 19 is periodically raised and moved forward, until it is again lowered and returned to its initial position. Thereby it is insured, that the splints 5 during their motion shall not be displaced with regard to the layer 28 of viscous igniting material, so that uniformly good heads can be formed at the ends of the matches. The dipping device for matchmachines described so far may be expected to work correctly. In cases, however, where for some reason or other it is desirable to feed the groups of match-splint carriers forward one after the other positively, this may be effected in the following manner.

A second shaft 37 (Fig. 3) may be dis# posed parallel to the shaft 9 and carries two like eccentric cam disks 3S and two other ones 40 (which may be assumed to be behind the cam disks 11, 12, 11, 12 respectively in Fig. This shaft 37 may be assumed to be driven from the match-machine at the same speed as the shaft 9 and in the direction of the arrow 39. Two like levers 41 and two other like levers 42 are mounted on the base plates 1, 1 to rock at 43 and are adapted to bear with their rollers 44 and 45 on the peripheries of the cam disks 3S and `40, against which they are constantly pressed in a manner to be presently described. Two vertical levers 46 are mounted on the base plates 1, 1 to rock at 47, and are pivotally connected on the one hand with the two levers 41 by means of rods 48 and on the other hand at their upper ends with two long pawls 49 and two other ones 50. All the match-splint carriers 4, 4 may be provided at their ends with recesses 51, 51 (Fig. 4) in which the noses 52 of the pawls 49 and those 53 of the pawls 5() can engage. Two other vertical levers 54 are mounted on the base plates 1, 1 on the right in Fig. 3 to rock at 55 and are pivotally connected on the one hand with the two levers 42 by means of rods 56 and en the other hand at their upper ends with two long pawls 57, which with their noses 5S can engage in the recesses 51, 51 of the match-splint carriers 4, 4. The two levers 41 are pressed to the left by weights 59 with the aid of chains 60 passing over guiding pulleys 61. The two levers 54 are equally pressed to the left by means of weights 62 attached to them by chains 63 passing over guiding pulleys 64. The eccentric part of the cam disks 12 eX- tending through the angle of b is made to coiirespond'with the respective part of the periphery of the cam disks 3S, and in a similar manner the periphery of the cam disks 40 is made to correspond with a part of the periphery of the cam disks 38. All the match-splint carriers 4, 4 are in this case charged with the match-splints 5, 5 and are fed forward in the rails 3, 3 by the known device mentioned above, while under the iniiuence of the cam disks 3S the two pawls 49 and 50 on the two levers 46 ride over the series of carriers 4, 4 until they engage one after the other with their noses 52 and 53 in the recesses 51, 51 of every first and ninth carrier 4 in each group, whereupon they will push the group of eight carriers 4, 4 at a rate slightly faster than that which the carriers 4, 4 on the left in Fig. 3 are fed forward, so that the two gaps 35, 35 will be formed for permitting the ledges 27, 27 on the table 19 to engage in them. The pawls 57 serve for detaching the carriers 4, 4 on the right from those pushed forward by the pawls 50, whereby the latterare assisted in their work. The cam disksv12 are again adapted to feed the table 19 forward with returned to its initial position.-

The dipping device can be varied in many respects without departing from the spirit of my invention. For example the two shafts 9 and 37 in Fig. 3 may be replaced by a single one, on which all the cam disks are fastened. `Where so preferred, the subsidiary pawls 57 with the levers 54 and all rthe parts connected therewith may be dispensed with.
